To all whom it may concern:

Be it known that I, GEORGE H. RUMKE, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Amusement Devices, ofwhich the following is a specification.

This invention relates to amusement devices, and its primary objectresides in providing a trackway for bicycles or motordriven vehicles,the continuity of which is interrupted by a vacant space or gap acrosswhich a vehicle driven along the riding surface, may leap by the forceof its momentum.

In order to prevent the vehicle from moving into the gap, especially oncurvilinear tracks, I provide at the forward edge of the same aninclined approach which directs the vehicle toward the portion of thedriving surface at the opposite side of the gap.

In the accompanying drawings in the various views of which like partsare similarly designated, Figure 1 is a plan view of a motordrome havingan annular driving surface, Fig. 2, a similar view of a similarmotor-drome showing a modified construction of the approach, and Fig. 3,a vertical section taken along the line 33, Fig. 1.

Referring to Figs. 1 and 3 of the'drawings the reference character 2designates a bowl-shaped motordrome, the driving surface of which iscomposed of a cylindrical, axially upright major portion 3 and aninwardly slanting minor portiont which con nects the main trackway withthe floor 5 of the structure and provides a surface along which avehicle circling within the motordrome, ascends.

The main riding surface has adjacent its upper edge, a gap 6, and at theedge of the gap forward with relation to the direction in which thevehicle moves along the track, an inclined approach 7 which projectsinwardly from the cylindrical surface.

It will be readily understood that a vehicle circling the drivingsurface at a high velocity, will when driven over the edge of theapproach, leap through space and across the gap by the force of itsmomentum and continue its course upon engaging the driv- 1ng surface atthe opposite side of the gap.

In the form shown in Fig. 1, the approach inclines gradually in a curvedline from the surface of the trackway, forward of the gap, while in theconstruction illustrated in Fig. 2, the surface of the ap proach isstraight and its deviation from the driving surface more abrupt.

It will be understood that the improved trackway may be made in formsother than those shown in the drawings and that the approach instead ofbeing made of a separate block fastened upon the trackway, may be formedby curving the driveway itself inwardly in front of the gap, or by anyother suitable method.

Having thus described my invention what I claim and desire to secure byLetters-Patent is:

1. In an amusement device, an annular riding-surface surrounding avertical axis, anda gap interrupting the continuity of said surface.

2. In an amusement device, an annular riding-surface surrounding avertical axis, a gap interrupting the continuity of said surface, and anapproach inclined from said surface toward said gap and terminatingadjacent the forward edge of the same.

3. In an amusement device, an annular riding-surface surroundingvertical axis, a gap interrupting the continuity of said surface, and 'acurved approach inclined from said surface toward said gap-andterminating adjacent the forward edge of the same.
